Cosine: AI-Powered Software Engineering for Developers

Cosine is an AI coding agent designed to empower developers by automating work directly within live codebases. As an agentic system, it operates end-to-end without human supervision, enabling developers to assign multiple tasks asynchronously and manage them efficiently. Trained to navigate complex production codebases like human engineers, Cosine breaks down abstract tasks into structured subtasks and deploys multiple agents simultaneously. It integrates seamlessly with popular workflow tools such as Slack, Jira, Linear, and GitHub, making it ideal for both individual developers and engineering teams. Powered by Genie 2.0, a proprietary model that outperforms OpenAI and Anthropic on the SWE-Lancer benchmark, Cosine delivers high accuracy and reliability in software development tasks.

Key Features:

• AI Coding Agent: Autonomous software engineer that retrieves data, plans solutions, writes and tests code, and collaborates in real time.
• Agentic System: Completes tasks end-to-end without human supervision.
• Task Management: Supports asynchronous task assignment and management, allowing users to assign multiple tickets at once.
• Codebase Navigation: Trained to understand and navigate complex production codebases.
• Workflow Integration: Integrates with Slack, Jira, Linear, and GitHub.
• Multi-Agent System: Breaks down large tasks into subtasks and deploys multiple agents simultaneously.
• Research Mode: Enables planning, issue investigation, and alignment across codebases.
• AutoDoc: Automatically generates documentation for code.
• CLI for Pair Programming: Command Line Interface for AI-powered coding assistance.
• Dashboard: Tracks usage metrics and project progress.
• File Mentions & Notifications: Enhances collaboration with real-time updates.
• Follow Mode: Allows users to monitor agent progress.
• Project Context: Tasks are executed within code repositories, providing full context.
• No Prompt Anxiety: Charges per task, not per prompt, with no additional cost for iterations.
• Data Privacy: Trained on publicly available open-source repositories; does not use customer data for training.
• Ownership: Users retain full ownership of their projects and code.

Pricing: Cosine offers a free plan with 80 tasks, access to all features, up to 100 projects, and no credit card required. After using 80 tasks, access becomes read-only until upgrading. Paid plans include Hobby at $20/month per seat, Professional at $99/month per seat, and Enterprise, which requires a demo. There is no pay-per-token pricing; costs are flat-rate and predictable.

Conclusion: Cosine is a powerful AI software engineering agent that transforms how developers work by automating complex coding tasks with precision and efficiency. Its agentic architecture, seamless integrations, and user-friendly pricing make it an essential tool for developers and engineering teams looking to accelerate software development while maintaining full control over their code.
